Application filed August 29, 1924.

To all whom it may concern: 7

Be it known that l, FELIX Knoenoorr, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of hllichigan, have invented certain new and useful improvements in Laundry Tubs, of which the following is a specification.

This invention relates to new and useful improvements in laundry tubs.

The primary object of the invention'is to provide a laundry tub, formed of reinforced plastic material, with folding or collapsible supports.

A further object of the invention is to provide improved means for uniting the tub structure and its folding or collapsible suports.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, t

Figure 1 illustrates a perspective view of the tub embodying this invention with its folding or collapsible supports operatively associated therewith and arranged in their et up or supporting positions,

Figure 2 illustrates in perspective the reinforcing framework of the plastic laundry tub and the folding or collapsible supports attached thereto,

Figure 3 illustrates a transverse sectional.

view of the structure set forth in Fig. 1,

Figure 41 illustrates a fragmentary end of the structure illustrated in Figs. 1 and 3 and-shown in front elevation for illustrating the manner of connecting and-bracing the supports for the tub when the latter are arranged in their set up or supporting positions,

Figure 5 is a similar view to Fig. 4: and shows the supports folded or collapsed against the bottom of the tub,

Figure 6 is a fragmentary sectional view taken upon line VI-VI of Fig. 3,

Figure 7 is a fragmentary end elevational view of one of the supports and shows the connection of permanent braces thereto, and

Figure 8 is a transverse sectional View taken upon line VIII-VIII of Fig. 7

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 5 desof these supports are Serial N0. 734,913.

ignates longitudinally extending base bars which are preferably of substantially inverted L-shape in crosssection. These longitudinally extending base bars are maintained in spaced relation to each other by the inverted U-shapedsupformed of angle iron ports 6 which are pivotally attached to the adjacent ends of the base bars 5 by bolts and nuts 4 and are formed of suitable angular material. The depending or leg portions 8 wardly diverging to the intermediate portion of the top 10 of the support and to the intermediate portions of the said legs 8. For the purpose of maintaining the supports 6 ing positions and for permitting them to be collapsed or folded against the bottom of the tub structure, to be described at a later point, the brace l are '11 are provided and pivotally attached to the intermediate portions of the depending legs 8, as illustrated. The remaining ends of these brace bars 11 are removably attached to the base bars 5, inwardly of their ends, by bolts and nuts 12. It will now beseen that a metallic stand has been provided which possesses foldable or collapsible supports.

The base bars 5 are provided with trans-- versely alined openings 13 through which entond the reinforcing rods 1 which are bent into substantially U-shape and have end portions extending perpendicularly from the base bars. Extending longitudinally of the stand previously ditional reinforcing rods 15 which have their bottom portions resting upon or suitably secured to the bottom portions of the reinforcing rods 14. These reinforcing rods 15 are also of substantially iJ-shapc, best illustrated i112. It will now be seen that a skeleton tub structure has been formed and permanently attachedto the base bars 5 of the collapsible stand.

The plastic materials, such as cement, concrete, etc, 16 is then suitably molded around the reinforcing rods 1i and 15 so that the said rods will be embedded therein, as best illustrated in Figs. 1, 3 and 6. During the molding of'this plastic material 16, a reinforcing, metallic top strip 17 is united with the plastic material 16 by means of the side walls or flanges 17 and the laterally inwardly projecting flanges 17 which form a part of the said stripl't',

It will be seen, by inspecting Figs. 3, l and braced by the downbars 9 which are connected in set up or supportreferred to are the adthe crating and shipping of the device.

5, that the upperlongitudinal portion of the base bars 5 are embedded in the plastic tub material 6 so that the said base bars 5 become unitary parts of the tub.

In Fig. 1 there is shown a transverse partition 18 which may be suitably formed and reinforced for formin a double tub, it being understood that a tub of any desired size may be made in the manner illustrated and divided into a desirable numberof compartments or sections by partitions 18.

It will now be seen that a laundry tub has been provided which is formed of reinil-oreed plastic material and foldable or collapsible supports have been secured to the tub structure in such a manner. that the supports may be rigidly braced for preventing oolla using of the same during the use of the tu or they may. be folded against the bottom of the tub, see Fig. 5, for permitting It that the manner of conand method of operating the launtubembodying this invention will be completely understood froni'the above detail description and that no further explanation is, therefore, deemed necessary. I

is now believed structing It is to be understood thatthe form of plastic material,

thisinvention herewith shown and described is to be taken as a preferredexample of the sameyand that size, and arrangement of parts may be resortedto Without departing from the spirit ofthe invention or the scope of the subjoined claims. p

Having thus described the invention, I claim 1. In a laundry tub, a tub formed of plas ticn'laterial having longitudinal base bars embedded in the tub and partially projecting' therefrom for mounting upon a support.

In a laundry tub, a tub formed 01 longitudinally extending angle base bars having one flange embedded in the tub and the other flange projecting therefrom for attachment to a support.

3. In a laundry tub, a tub formed of plastic material, a metallic reinforcement for the tub. including longitudinal base bars of angle formation embedded therein, brace rods supported by the base barsland one flange of each angle base bar entendiii'g outwardly of the tub body for attachn ient to a support. 7 l V In testiu'iony whereof I aiiix niy si "1'1ature.
